VBe itknownthat I, 'HANS Jon-risoN,a

citizen of the UnitedYStates-ot America7 residing 'atlDortV JedersonStationn athe.'

county oi Suffolk and State: ov'NeW York, have invented .,certainxnewand` 'useful .Ini-` provements in .alSeWage-Disposal Apparatus; ofwhichlthe following isaull,V clear! and exact[specitication.V 1 f My inventionrelatesjto a sewage/disposal apparatus Vand more particularlytoQa'septic Y K particularly, in Y 2, which farev laidvwith tank 'forthe purification of sewage? bysedi mentation and theaction-ofjanerobic.-bac-p In apparatus ofthis type,sewage"isipurified'fby the action of -niicro-organisms-,f such asanerobic bacteria, which propagate Y out of contact with light and yairand convert the polluted Water-carrying"objectional organicmaterial to`a purified form. Such an Vapparatus ordinarilyv comprises' a septictank sunk beneath the surface of the ground Where the liquid may bepermittedv toA stand Vand thesolid matter settle' out by"eedirnen-vtation andthe Whole mass digested by bac'-4 terial action. -The puriedliquid'is drawn`4 ofi'rfrom the settling` chamber and permitted to soakawayY into the adjacent porous earth.

Itis the prime object of inveizition'to provide a `simplified and'yeconomically built sewage disposal apparatus which issuitable'- for usein'Y various types*otearthl Vformations' andWillservetov dispose ofsewage eiiicient# ly and for a long period of time. n With'tliis andfurther objects inviewy'as Will'be apparent from the .followingdisfclosure, my invention resides inthe combination of parts set orthcinthespeciiication and covered bythe claims appended liereto. p y p theWall 16 are disgosedfat aconsiderable.

The level of the fiuidin theseptic tank remains at a constant level -While the level of the `Huid.inthek reservoir mayvary depending uponthe amount of water flowing intothe tank. `Hence, the tank reservoir and the outer-annular gravel filledzone provide a large space which willY take care of excessive amounts ofwater lowingV into the tank and permit the water to seep away duringperiods when the' amount of incoming Vwater is at a minimum. c

Having thus described my Y invention,

what I claim asnew and desire tosecure Y by Letters Patentvisz- 1 Yl. Asewage disposal apparatus comprising a septic tank located in anearthpit and sur-VK rounded by an annular gravel filled .Zone

Vwhich communicates directly with the-adjacent earth, an infiperviouslpartition 'dividing the tank Vin two compartments, ythe wall on one sideof the partition being iinQer-Al.` vious, a floor cooperating with saidparti-j tion and impervious wall to Jform a bacterial digestion chamber,Athe Vtank wallon the other side of the partition having openingstherethrough to said zone and forming a storage reservoir, 'a cover forthe tank, mea-ns for introducting sewage into the dil vgestion chamber,and means providing an f overflow passage from said chamber tothereservoir.

2. A septic tank coinprisingan enclosing wall setin an Vearthpitandhaving'outwardly projecting'ribs, the spaces lbetween which form atransfusion zone, an imper-V vious wall within the tankcooperating-therewith to form a digestive 'chamber and Y a reservoir,said reservoir being Yadaptedto receive the overliow from said chamberand f communicating with the outer zone.

3. A septic tankl comprising a wall of L- shaped blocks arrangedfwiththe legsprojecting outwardly to form vertical channelsY adapted to befilled vwith gravel, means cooperating wi'th said tank wall to` form. an
